@meleu , what do you think? Would it be possible to add something like that to your script?

@Halvhjearne
That's the thing I didn't want to do, but...

So I saved all the data from my Pi, formatted the USB key, and installed a fresh version of retroPie: I was able to configure the controller.
Then I updated the system and RetroPie, tried again to configure the controller: it worked this time again.
I restored all the games now, and it's still working.
I don't know what was the problem, but now it's gone

Thank you all

Many thanks for the info on evdev. I thought it wasn't being used since evdev-joystick --l doesn't show anything, but the gamepad was being assigned to /dev/input/eventX

I ended up using this solution:

Thanks, somehow I missed it.
facepalm

@imran7junior Please don't bump old topics - even if remotely connected to your problem. Open a new topic and add the info requested in https://retropie.org.uk/forum/topic/3/read-this-first.

@hushkin Instead of re-flashing you could just reset the controller configuration and start over with it. You can reset them from the emulationstation package in the RetroPie-Setup script. After that, ES should prompt you to re-configure them again. Try starting with the problematic controller and see who it behaves.

@jacreason Did you ever figure out how to do this. I just bought the same board and want to be able to two player xinput (gamepad) and also one player with two stick play if I can with it.

@mitu said in SNES Start button not working, USB controller:

@kamban Can you try to remap one of your controller from RetroArch - does Select + X bring up the RetroArch Gui ?

Yes, GUI shows up. I checked the controls and see
Auto: 8 (N/A), (Key:rs... Select

as well as the other mapped keys. Also tried another SNES rom, same here. I really have no idea why the select is not working...

Thank you! Worked for me

@benniebax
Bind the Player 3 keys if your controller says is the 3rd

Hi,

I just tried that, it has the same effect.

I don't know how to help but I would recommend that you try lr-vice. It's considered experimental but it works fine for me and benefits from RetroArch's control and shader goodness.

@mitu okay, cool I'll give that a shot. Cheers.

@mediamogul
thank you, I will try them

@gtoilet if you mean the configure a controller screen, the info you want is in the docs: https://retropie.org.uk/docs/RetroArch-Configuration/

Scroll down to the bit where it shows the controllers and what each button on them corresponds to in retroarch. That'll show you what to map each N64 button as. Anything else you don't have on the 64 pad, hold any button on the controller to skip it.

@mitu

thank you, I appreciate the information. sorry, i skimmed the read first, must've not been paying attention.

@simonster yes, that is exactly the problem. Thanks for the walk through!
